STANDARD-RIG: CONSTRUCTION.

Application led January T0 all 'whom t may concern.'

Be it known that I, LLOYD E. LEWIS, a citizen of the United States,residing at Shreveport, Louisiana, have invented a certain new anduseful Improvement in Standard-Rig Constructions, of which the followingis a specification,

My invention relates to standard rig equipment for well operations.

I have Jfound that the usual standard rig is subject to many objectionsbecause of deects in construction. The wooden structure ordinarilyemployed to support the operating means will warp under strain and 1talso quickly deteriorates and breaks under wear and decay in adverseweather conditions. Thus the belts or chains are thrown out of line andthe posts are subject to breakage under side strains set up where thebase is thrown out of alignment. Attempts have been made to form a moredurable and lasting structure but the expense of heavier woodenconstruction is great, and the diiiiculty of keeping the parts inal1gnment is not overcome.

I have, as an object of my invention, to construct a irmand substantialhase of concrete which will be of one integral piece and hence notsubject to be moved out of alignment. To form the base of concrete ithas been necessary to modify the remaining` structure in certainessential respects as will appear.

I also desire to construct the body of the supporting structure ofmaterial easily obtained about the usual oil well operating equipment.

Certain other objects and the means by which they are accomplished willmore clearly appear from the description which follows.

Referring to the drawing herewith Fig. 1 is a side elevation, certainparts being in vertical section, illustrating a standard rig employing`my invention. Fig. 2 is a vertical section of the upper end of theSamson post and walking beam. Fig. 3 is a horizontal section on theplane 3 3 of. Fig. 1, Like numerals of reference are employed todesignate like parts in all the views.

In adapting the standard construction for manufacturing it of concretein one unitary structure, it is necessary that certain essential changesin the construction of the rig be made. The usual standard rig which 10,1925. Serial No. 1,692.

may be employed either in drilling by the reciprocating method, or forpumping the well after it has been drilled. It includes a Samson post 7with a walking beam 2 supported on the Samson post for a rocking motion.It also involves the use of two spaced jack posts upon which isjournaled a shaft to which the usual rig irons are se` cured. Icontemplate uniting all of these parts of the rig in as nearly integralconstruction as possible, and also desire to form both the jack postsand the Samson post of pipe of a standard construction such as may befound about the usual oil well.

In carrying out my invention I form a transverse base 1 for the jackpost. This base is of solid concrete, and has thereon spaced blocks 2elevated somewhat above the base for supporting the jack posts 3.

To more firmly anchor the base 1, and to prevent any change in positionwith the base, I construct two longitudinal cross members t and 5projecting from the base 1 in opposite directions. The longitudinalmember 4 projects equal distances in each direction from the base. Themember 5 however is extended materially beyond the member 4L upon oneside to connect with a block 6 forming a support for the Samson post 7The two longitudinal members l and 5 are reinforced b. transverse rodsor bars 8 and 9 on each si e of the base 1 and parallel therewith. Theserods are embedded in the cement and act to hold the longitudinal membersin rigid alignment.

In order to construct the jack post 3 of ordinary pipe construction, Ihave devised a base plate 10. This plate has central openings therein toreceive a plurality of stay bolts 11, the lower ends of which are hookedand anchored into the cement when the base is cast, and the upper endsof which are threaded at 12 to receive nuts by means of which the plateis held embedded within a seat 13 formed in the cement to receive thesame. It will be noted that the plate may be removed if necessarywithout inter fering with the concrete base in which it is seated. Theplate 10 is formed with a central circular boss 14 thereon adapted tofit within the tubular posts 3.

The posts 3 may be of the usual height suitable for ordinary welloperations, and are adapted to be fitted within and secured to the lowerbearing plates 15. Each bearing plate is of the usual constructionhaving a bearing recess 16 therein to receive the cross shaft 17 uponwhich the usual rig irons and crank arm are mounted. A top bearing plate18 serves to hold the shaft firmly in position. Both bearing plates aresecured together by through bolts 19, and also by rods 2O extending fromsaid plates downwardly and secured through a C link 21 to the anchorbolts 22 embedded in the cement base. The posts and the bearing platesare, however, reinforced and braced by laterally inclined rodS 23 and 24on each side thereof, said rods including a centrally turnbuckle 25 anda lower eyelet 2 6, secured in anchoring bolts 27 embedded in the crossmembers 4 and 5 at points spaced a desired distance away from the jackposts.

The Samson post 7 is secured upon the supporting block 6 in a mannersimilar to that employed in connection with lthe jack posts. There is abase plate 10 embedded in the upper face of the block and anchored inposition by means of stay bolts 28 as previously described, the uppercircular boss 14 on said plate lits within the central opening of thetubular post 1. The post is anchored in position, however, by means ofrods 29 connected at their upper ends to a diametrical bar 30 passingthrough an opening in said Samson post. The lower end of said rods aredetachably secured to the stay bolts 3l, embedded in the cement asclearly shown in Fig. 1.

The Samson post is also braced by means of the inclined brace bars 32,which are fitted at their upper ends within a notch or recess 33 formedin the side of the Samson post and the lower ends of which are seatedwithin notches or recesses 34 formed in the base 5. There is also a rod36 connected at its upper end to the Samson post, and at its lower endto stay bolts 37 anchored in the base member 5. A turnbuckle 38 in saidrod 36 allows the tension thereon to be adjusted as occasion arises. TheSamson post is formed with ahead 39 thereon which is formed of twosimilar side members spaced apart by means of a. plate 40 and adapted tofit at their lower ends within the upper end of the Samson post. Theyare securely held in position in said post by means of transverse bolts41 extending diametrically through said Samson post and the three partscomprising the bearing member. The upper ends of the two parts 39 areformed to receive the shaft 42 and to lallow a rocking movement of saidshaft It is contemplated that the ends 44 of the' walking beam will bepositioned over the jack posts in such manner as to connect with thecrank arm on the shaft 17 for operation in the usual manner, and thatthe Opposite end of said walking beam may be connected to the drillingapparatus or the pump rod in the customary manner.

The advantages of this type of construction are numerous. It serves toform a solid unitary construction out of material which may be readilyassembled and erected within the oil fields` t supplies a firm basewhich will not get out of alignment and will not deteriorate in use. Thestructure is essentially a cheap and economical one, and itsconstruction simple and rugged.l It is necessary however to have certainspecial parts which have been described forming eatures of novelty whichare set forth in the claims.

While I have shown a concrete embodiment of,my invention, I wish itunderstood that certain changes may be made therein coming within thescope of the claims, and l do not wish to be confined to the eXactdetails above described.

What I claim as new and desi-re to protect by Letters Patentis:
